The thermal stability of alkaline earth metal carbonates–MgCO3, CaCO3, SrCO3 and BaCO3, follows the order(A) BaCO3 > SrCO3 > CaCO3 > MgCO3(B) CaCO3 > SrCO3 > BaCO3 > MgCO3(C) MgCO3 > CaCO3 > SrCO3 > BaCO3(D) SrCO3 > CaCO3 > MgCO3 > BaCO3 |
Answer» Correct option (A) BaCO3 > SrCO3 > CaCO3 > MgCO3 Explanation: Thermal stability of polyvalent anion salt like CO32– increase down the group due to increase in ionic character |
